Rat Control City of London
Rats in the Square Mile are usually a drainage or basement issue beneath office blocks and food premises rather than a garden problem.
Pest Control London 24 provides pest control across the City of London for offices, food premises, livery halls and the small number of residential buildings in the Square Mile, including the Barbican Estate. This hub brings together the main pest services, published prices and local-area pages in one place.
The services on offer cover rats, mice, wasps, bed bugs, fleas, cockroaches, ants, squirrels, carpet moths, carpet beetles and spiders. There's also a rodent-proofing service for smaller, accessible gaps. To arrange pest control in City of London, call 0800 955 2347.
The City of London is unlike any other borough we cover — a working financial district of offices, livery halls and historic buildings, with only a small resident population. Pest problems here are overwhelmingly a commercial matter.

The office towers and banking halls around Bank and Cheapside have basement plant rooms, service risers and staff kitchens that mice and cockroaches can use to move between floors. A single desk sighting is often worth investigating at basement or kitchen level rather than treated as an isolated event.

Smithfield's historic market buildings and the dense cluster of restaurants and food outlets around Aldgate bring the City's most frequent pest call-outs — cockroaches and ants following waste routes and warm pipework between kitchens, cellars and neighbouring units.

Livery halls, churches and other listed buildings around St Paul's and the surrounding lanes have old roof voids, wall cavities and rarely disturbed storage rooms. Carpet moths and spiders build up in spaces like these, and any treatment has to work within the constraints of a listed structure.

The Barbican Estate is the City's main pocket of homes, with flats served by shared walkways, communal stores and service risers running through the towers. Call 0800 955 2347 with the block and flat number so we can plan access with the estate office where needed.

Rats in the Square Mile are usually a drainage or basement issue beneath office blocks and food premises rather than a garden problem.

Mice move through service risers and basement plant rooms in office buildings, and through shared floors in the Barbican Estate.

Nests occasionally build in roof voids and window recesses on older buildings and in the Barbican's raised walkway planting. A flat fee, with a 30-day guarantee attached.

The Barbican Estate and the small stock of residential blocks around Temple are where bed bug call-outs occur, usually room by room.

Flea call-outs are rare in the City, generally limited to the residential flats around the Barbican with a history of pets.

Dense clusters of food premises around Smithfield and Aldgate give cockroaches a route between kitchens, cellars and waste stores.

Ants turn up in ground-floor kitchens and basement staff areas of offices and food premises, coming in through service entrances.

Less common in the Square Mile's built-up core, though the gardens and mature trees near Temple can bring squirrels onto nearby roofs.

Historic livery halls and older buildings with wool carpets and hangings in rarely disturbed rooms are prone to carpet moths.

Fitted carpets in offices and the residential blocks of the Barbican Estate are a common site for carpet beetle larvae.

Basements, plant rooms and rarely used storage areas beneath office buildings are where spider numbers tend to build up.

In the City of London, wasp nests occasionally turn up in roof voids on older buildings and in the raised planting around the Barbican's walkways. The whole job is a flat £90, and if the nest is still active within 30 days, we come back at no extra cost.
We charge £180 for up to one hour, small holes for rodent proofing. It works on accessible gaps around a property that rats or mice might use to get in.
In the Square Mile's office buildings that usually means gaps around service risers, basement plant rooms and loading bay doors.
In the Barbican's residential blocks, gaps around meter cupboards and communal service ducts are common entry points that proofing can close off.
